Title: Finishing knitted fabric contg synthetic fibres by hot pressing - to deform synthetic fibres, and after cooling, reheating
IPC: D06C15/02
Filed: 1975-11-12
Abstract: A knitted fabric contg. synthetic fibres in hot-pressed e.g. by passage through the nip of a pair of presser rolls of which one at least is heated and the fabric is then cooled by e.g. an air flow, to fix the synthetic fibres which are deformed by the hot pressing. Subsequently the fabric is re-heated to relax the internal tensions in the deformed synthetic fibres. The finished fabric has a greater density and stability and a smoother surface having a reduced tendency to pile.

Patent FR-2356236-A1 (FR)
IPC: G11C13/04
Filed: 1976-07-26
Abstract: In order to be able to write information in a medium (1), a first laser beam (3), which comes from a beam-intensity control and deflecting device (5), is directed through the medium (1). A second laser beam (4), coming from a second beam-intensity control and deflecting device (6), is directed through the said medium (1) in such a way that the two laser beams intersect. The first laser beam sets the medium in a first state of excitation. In the region of intersection (2) of the two beams, the second laser beam sets the thus sensitised medium with a changed monomolecular absorptivity in comparison with the initial state. In this way, by means of a computer (9) which controls the said deflecting devices (5, 6), information can be stored in the medium.

Title: Hydraulic cylinder with precision piston positioning - has profiled sleeve over exit on balancing cylinder rotated to externally change equilibrium position
IPC: F15B9/08
Filed: 1976-07-30
Abstract: The hydraulic cylinder (1) with the facility for precisely positioning the piston (2) is fed with oil through the pipe (3) into the annular space (A). A drilling (2d) allows oil to flow into the annular space (D) inside the piston and thence through a restrictor valve into a further internal chamber (c). An exist drilling from this chamber (2e) allows the oil to escape to a return pipe (6). Around the piston at this point is a profiled sleeve (8) fixed in a casting (9) which is turned externally via a worm wheel (14) and worm gear. As the sleeve (8) is rotated, it moves the position at which the exit drilling (2e) is uncovered, and thus the position of the piston at which equilibrium of pressure exists between the two sides (A, B) of the piston (2).

Patent FR-2325818-A1 (FR)
Title: Electronic pre:ignition system for IC engines - generates control pulses by comparing reference pulses for each working cycle
IPC: F02P5/15
Filed: 1976-09-20
Abstract: The pre-ignition system uses pulses derived from a reference angle on e.g. the crankshaft. The reference angle pulse repitition frequency corresponds to the engine speed. A separate continuous pulse train is generated whose pulse repetition frequency is independent from the engine speed. Pulses of this pulse train are counted between two consecutive angle reference pulses. They are simultaneously counted back between two consecutive reference pulses. The countdown starts at the number of pulses counted in the immediately preceding cycle, and a control signal is delivered when the countdown reaches a specified threshold. The ignition sequences may be altered by using a data store to change the time when the control signal is delivered.

Title: Control of triac in series with motor load - utilises load current inversion detector to control triac switch
Inventor: GUERIN-PINAUD JACQUES
IPC: G05F1/45
Filed: 1976-11-18
Abstract: A triac in series with an AC mains supply switches and controls a motor in household goods such as a washing machine. Parasitic RF radiation and motor torque variations are reduced by a current inversion detector circuit in series with the mains supply. An alternating current flowing in a motor (3) via a triac (5) develops a voltage across a low value resistor (4) with shunt diodes (6, 7) and connected to two conductor rails (11, 31). This voltage is applied to two transistors (29, 30) whose bases are connected to two conductor rails (10, 11) forming a current inversion detector. The transistors alternately conduct and are blocked depending on polarity of voltage across the resistor (4). The triac conducts only when both transistors conduct together.

Abstract: The laser scanning apparatus is used for scanning an original colour document with light of three different colours. In a first operative sequence, the output beam from a laser, which comprises light of a first colour, is incident upon a rotating scanning member. The light is directed to a reflecting first portion of a luminescent screen, the light reflected from the first screen portion completely scanning the entire original document. In a second operative sequence, the laser light from the rotating scanning member is directed to a second portion of the luminescent screen. There is a material associated therewith which produces light of a second colour in response to the incident laser light, the light produced by the second portion of the luminescent screen scanning the entire original document.

Title: PIN type semiconductor diodes - are fabricated using heat treatment to obtain desired resistance loss characteristics
Inventor: DAVID GERARD ROBERT
IPC: H01L29/868
Filed: 1977-02-23
Abstract: A method is used for fabrication of a semiconducting diode of the PIN type from a chip of semiconducting material. The semiconducting material has at least three superposed layers, one of which has a first type conductivity, an intermediate layer of relatively thick and high resistivity material, and a layer of opposite conductivity to the first. The diode is cut in the material by abrasive mechanical systems which remove at least all of the thickness of the intermediate layer. The diode is then subjected to heat treatment. The diode is brought to a temperature for a sufficient period of time to modify the loss resistance of the diode. The heat treatment is carried out in an atmosphere containing hydrogen and a neutral gas. The temperature of treatment is between 300 deg. C and 500 deg. C for a time of 10 to 60 minutes.

Title: Heat engine operating over small temp. difference - has two units which draw water alternately from power station cooling water discharge and river to expand and contact solid or hollow body
IPC: F03G7/06
Filed: 1977-03-25
Abstract: A power station (1) receives cooling water from a river (2) and returns (6) this water to the river. Two auxiliary heat engines (3, 4) draw water alternatively from the cooling water return of the station (1) and directly from the river. The temperature of the water they receive thus alternates between two fairly close values. In each engine the water flows over a solid body or a container of gas or liquid. The hot stream causes the body to expand and the cold stream causes it to contract again. This movement is amplified either by gears or by levers to give a usable output of adequate proportions.
